Definitions

  • thermoplastic polymers of the type for example of block elastomers [SBS, SEBS (for Styrene Ethylene Butadiene Styrene), . . . ] or plastomers [Polyolefin of the type of PPA, EVA, PPI, APAO (for amorphous a polyolefin)].
  • SBS block elastomers
  • SEBS for Styrene Ethylene Butadiene Styrene
  • plastomers Polyolefin of the type of PPA, EVA, PPI, APAO (for amorphous a polyolefin)].
  • French patent No. 2 064 750 discloses a thermoplastic bituminous binder containing up to 10% of polyurethane.
  • the polyols used have functionalities greater than 2, up to 8.
  • the binder keeps its thermoplastic properties because of the low proportion of polymer.
  • a sheet material forming a barrier against moisture and comprising a layer of a mixture of bitumen/polyurethane spread on a polymeric film and covered with a detachable film.
  • the problem solved by the present invention consists in providing a prefabricated sealing membrane based on modified bituminous binder, that can be produced in an industrial manner according to the current techniques of spreading or impregnation, such as calandering (if desired slightly modified), adapted to be softened by heating before emplacement without modification of its characteristic, having a high stability against UV (ultraviolet) and a high resistance to oxidation and aging and being exposed to atmospheric and climatic aggressive agents.
  • thermoplastic polyurethane whose prepolymer can if desired be prepared in advance, is obtained from diisocyanate of a functionality substantially equal to 2, of polyol of a functionality substantially equal to 2, and of a chain lengthening agent.
  • the polyol could be selected from polyesters, polyethers and polycarbonates of a functionality substantially equal to 2 and of molecular weights of 1000 to 5000, preferably comprised between 1000 and 3000. These polyols could be used alone or in combination, which is to say mixed together.
  • the thermoplastic polyurethane is preferably constituted by a quantity of hard segments (% by weight isocyanate +% by weight chain lengthener) comprised between 10 and 40%, preferably between 10 and 30%, and the ratio of isocyanate/polyol is comprised between 1.0 and 1.1 and is preferably about 1.05.
  • the catalyst could be selected from catalysts currently used in the synthesis of polyurethanes and known to those skilled in the art.
  • the filler will be selected from mineral fillers such as chalk, silica, talc, dolomite, kaolin and possible mixtures of at least two of these substances.
  • the present invention also has for its object a process for the industrial production of a sealing membrane as described above.
  • bitumen According to the type of bitumen, it can be that the latter, because of the presence of reactive groups in the fraction of asphaltenes, consumes a portion of the isocyanates. It is then necessary, in the case of the synthesis of the prepolymer in the bitumen (synthesis in one pass), to take account of this reactivity and to adjust the quantity of isocyanate to be used.
  • Tests are carried out to determine the TBA, the penetration at 25° C., the Theological properties with a range of temperatures, the cold flexibility and the mechanical characteristics by direction traction.
